l Vhile we have illustrated and described our invention with some degreeof particularity, we realize thatin practice various alterations thereinmay be made. We there- 'lor'reserve the right and privilege of changingthe details of construction or otherwise altering the arrangement of thecorrelated parts without'departing fromthe spirit or the scope of theappended claims.

. Having thus described our invention what we 'claim' as new and desireto secure by United States Letters Patent is:

1. In combination with, a railway 'track provided-with zones, a'signaldevice on locomotives, andmeans for operating the sigequipped withcontact discs eleetrically connected to certain parts ofthe signaldevice.

2.- In combination with a locomotive and a rail contact truck, a framefor the rail contact truck, contact arms secured'to the frame, a bentrod pivoted to the frame, and having its ends engaged beneath certain ofthe contact arms, a connecting rod attached to the bent rod, a-bellcrankpivoted to the locomotive, the free end of the connecting rod beingattached to one arm ofthe bell crank, a rod slidable on the other arm ofthe bell crank, a handle on the upper end of the rod, and a serratedsegment attached to the locomotive, thebottom end of the rod beingengageable in the serrated segment. 8.-In combination with a locomotiveand a rail contact track, a frame forthe rail contact truck, contactarms secured to the frame, leads connected withsaid contactarms, asolenoid operated signal device in said" locomotive, and said leadsbeing connected with said solenoid, a bent rod. pivoted 'to the.

bell crank. a rod slidable on the other arm of the bell crank, of therod, and a to" the locomotive,

a handle on the upper end serrated segment attached the bottom end ofthe rod eing engageable in the serrated segment.

"4. The combination with a locomotive having an automatic signal devicefor detecting when another similarly equipped locomotive enters the samerail zone, of a frame connected with the locomotive, a rail contacttruck attached thereto, contact arms secured to the frame, leadsconnected with said contact arms. and with said automatic 1 signaldevice, a bent rod pivoted to the of the rod, and a serrated segmentattached frame, and having its ends engaged beneath to the-locomotive,the bottom end of the rod 10 certain of the contact-arms, a connectingrod being engageable in the serrated segment. attached to the bent rod,a bell crank pivoted In testimony whereof We have aflixed our to thelocomotive, the free end of the consignatures.
